The ecological challenge
One of the requirements of the National Environmental Protection Agency was the movement of the coral threatened by the work. Before the entrance channel to the port could be deepened, 24 different types of hard coral had to be transplanted: 150,000 individual pieces in total. The conditions in terms of light intensity, the speed of water currents and temperature at the new location had to be as close as possible to the conditions in the original location. The corals were moved to suitable locations between 500 and 1500 meters away.
